Abstract:

Multimedia applications are becoming increasingly significant in modern world. The mushroom growth of multimedia data of these applications, particularly over the web has increased the demand for protection of copyright. Digital watermarking is much more acceptable as a solution to the problem of copyright protection and authentication of multimedia data while working in a networked environment. In this paper, a DWT based watermarking scheme is proposed. We have used Genetic Algorithm (GA) in order to make an optimum tradeoff between imperceptibility and robustness by choosing an optimum watermarking level for each coefficient of the cover image. In addition to the suitable watermarking strength, the selection of best block size is also necessary for superior perceptual shaping functions.......Keyword: Steganography,Watermarking,Discrete Wavelet Transform,Genetic Algorithm, Peak Signal to noise Ratio, Data Hiding..

Abstract:

The rapid expansion and intricacy in the construction industry cause difficulties in maintaining performance, time, and quality services of a construction project, which leads to the failure to meet the scope and objective of a project. In addition, improper planning, widespread dependence, and low availability of materials increase the cost of the construction project. To manage such issues, Project Management Consultancy is one of the management solutions that have been widely used. Project Management Consultancy plays a multifaceted role in providing services from the beginning of construction to its completion. Project Management Consultancy makes sure whether we are moving in the right pathway according to the planned schedule.Keywords:Project Management Consultancy (PMC), Water Scheme Project, Risk factors by PMC, Collector well, Construction industry

Abstract:

In the open access restructured power system market, it is necessary to develop an appropriate pricing scheme that can provide the useful economic information to market participants, such as generation, transmission companies and customers. Though many methods have already been proposed, but accurately estimating and allocating the transmission cost in the transmission pricing scheme is still a challenging task. This work addresses the problem of allocating the cost of the transmission network to generators and demands. In this work four methods using DC Power flow and AC power flow have been attempted. They are MW-Mile Method, MVA-Mile Method, GGDF method and Bialek Tracing method..Keywords:....

Abstract:

Now a day's in RCC (Reinforced Cement Concrete) structure as an open first storey is generally provided for social and functional need in multistory building. They are used for parking, communicaton halls, intercourse hall or any other purposes. In RCC framed multistory building the walls are not considered as a part of structures, but from recent studies it shows that partition wall by using different infill materials helps to improve the strength of building against lateral load. An infill material provides stiffness to the RCC framed structures. Soft storey at different levels of multistory building is constructed. Investigations of past and recent earthquake damage have illustrated that the building structures are severe damage or collapse during moderate to strong ground motion. In this paper reviews various research works carried out by several researchers on seismic behavior of multi-storied buildings provided with different infill materials with soft storey..Keywords:Multistory building, infill materials, seismic behavior, RCC frame

Abstract:

The analytical research carried out to study the behaviour flat slab building with and without shear wall reported in the present work. For analysis 15 storied flat slab building is analyzed for seismic behaviour. Response spectrum method is used for analysis considering different shear wall positions using ETABS software. Five different positions of shear wall were studied for analysis. From this analysis shear wall at core having square shape is most suitable case for construction of shear wall.Keywords:Flat slab, Shear wall, Seismic behaviour.

Thermosolutal convection in Maxwellian viscoelastic fluid under the simultaneous effects of uniform vertical
magnetic field and suspended particles through porous medium is mathematically investigated. A sufficient
condition for the invalidity of the 'principle of exchange of stabilities' is derived, in the context, which states
that the exchange principle is not valid provided the thermal Rayleigh number R.......Keywords:Maxwellian viscoelastic fluid, porous medium, suspended particles, thermosolutal convection,

Abstract:

The objective of the electric utility is to
deliver sinusoidal voltage at fairly constant
magnitude throughout their system. This objective
is complicated by the fact that there are loads on
the system that produce harmonic currents. These
currents result in distorted voltages and currents
that can adversely impact the system performance
in different ways. As the number of harmonic
producing loads has increased over the years, it has
become increasingly necessary to address
their influence when making any additions or
changes to an Installation............Keywords:...

Abstract:

Medical Big Data (MBD) consists of very useful type of information. It is very important for a physician for decision making and treatments to cure the patient. For accurate diagnosis, data availability is the most important factor. MBD over network needs intelligent compression schemes so that it is transferred to the destination by utilizing available bandwidth. Wavelet Compression schemes compress the MBD without losing the important information, thus making the information reliable and less in size.Keywords:Medical Big Data, Haar, Orthogonal, Biorthogonal, Wavelet Compression.

Abstract:

The optimal digital autopilot needed to control of the roll for an aircraft in the presence of an arbitrary unmeasured disturbances is addressed in this paper. Such autopilot has to achieve a desired lateral motion control of this aircraft via minimizing the upper bound on the absolute value of the difference between the given and true roll angles. It is ensured by means of the two digital controllers. The inner controller is designed as the discrete-time PI controller in order to stabilize a given roll rate. This variable is formed by the external P controller. The necessary and sufficient conditions under which the two-circuit feedback discrete-time control system will be stable are derived. To optimize this control system, the controller parameters are derived utilizing the so-called l1-optimization approach advanced in modern control theory....Keywords:Aircraft, Lateral Dynamics, Digital Control System, Discrete Time, Stability, l 1-Optimization, Random Search Algorithm, Robustness

Steering wheel vibration is one of the major factor in determining the operator's comfort in an agricultural tractor. Over the past 20 years automobile quality and consumer perceptions and demands have been an increasing part of the vehicle engineering process. This project deals with study of vibration related issues in steering wheel of tractor. The design and analysis of steering system plays a major role for determining the root cause for the problem. Main sources of steering wheel vibration are found to be engine imbalance, resonance of steering system, lesser damping, road / field induced vibration. Steering vibration study was conducted on various tractor models and one tractor was identified for improvement...Keywords:Steering wheel, vibration, dampers, frequency, resonance, amplitude.

Abstract:

Pakistan is endowed with a vast variety of minerals including coal. However, despite its significant amount of coal deposits of about 186billion tons, no significant contribution to the country's GDPhas been realized from this resource. Also, in the face of the possession of this 'richness' in coal deposits, the country is still facing acute shortage of electricity, which wipes off about 2% of GDP annually. The current deposits of coal can give Pakistan its much needed social and economic boost. Unfortunately, Pakistan has not been able to utilize its Thar coal potential fully since its discovery in 1992, for instance, due to policy issues and other concerns. This paper investigates the current markets, trends and utilization modes for Pakistan's coal with reference to the reasons for failure of the Thar coal project as well as opportunities available for Pakistan, going forward.Keywords:...........
